option 49 is used on switch/firewall when u configure a dhcp server on it. it allows you to direct the trafic of this pool to some specific server. With option 49 array , u can give a list of servers which will be attempted by client to contact in the order of sequence which u have used..e.g
set system services dhcp pool <ip subnet of pool> option 49 array ip address [ < ip addresses of servers to be contacted by client > ]
i hope it would clarify ur query.....
